Tried to add unassigned 120GB drives to A In ACU: Would only allow me to make a signle new array using the drives. (No option to manage / expand)

In MCU, tried comand: ctrl slot=0 array A add drives=1I:1:3-1I:1:4. Results:Error: This operation is not supported with the current configuration. Use the"show" command on devices to show additional details about the configuration.Reason: Transformation size zero. This may indicate that there is no battery or a failed battery on the controller.

According to my research, the 420i should permit this operation?

Dont want to start from scratch and restore from backup. As of now, that appears to be my only option. Very dissapionted in my P420i capabilites. Am I missing some type of feature? All suggestios appreciated!

Re: Expanding Raid Array: DL360 (733732R-001) With Smart Array P420i

The SKU# you've listed ships as a P420i/ZM controller. FOr advanced features such as expanding an array you need a cache module. Any of the three FBWC modules you've listed will work with the controller.
